eAs-GENERATlNc LAM P.

SPECIFICATION forming part of Letters Patent No. 567,773, dated September 15, 1896. Application filed August 1, 1895. Serial No. 557,913. (No model.) Patented in England J'une 1'7, 1895, No. 11,783.

invented a new and useful Gas-Generating Lamp, (for which I have obtained a patent in Great Britain, No. 11,783, bearing'date J une 17, 1895,) of which the following is a specification.

My invention relates to a gas-lamp in which",

carbide of calcium is subjected to the action of water, so as to generate what is called' acetylene gas, to be burned in my lamp, the said gas being combustible and ot' a high lighting power; and the object of my invention is to provide means by which the supply Vofthe water is automatically regulated by thepressure of the generated gas, so as to give a uniform and quiet iame without daring or sooting.l I attain this object by the arrange ment illustrated in the accompanying drawing, which is a vertical section of the entire lamp.

ny is a close vessel containingv a gasonieter bffrom the top of which project a supply or inlet pipe for the water and a central guidetube, both extending through the cover of vessel cl. The gasonieterb is open at the bottom and dipsinto the water supplied by the inlet-pipe, the level of the water entering the gasolneter being obviously depressed as conipared with the outer wateielevelby reason ot' and in proportion to the pressure of air or gas contained in the gasometer, as shown in the drawing.` Avpipef extends through and is guided within the above-mentioned guidetube and is held at its place by friction. Pipe f is provided with small openings at its upper y end, through which escapest-he gas to be burned. y

g is a receptacle for water connected to a frame, which is supported by the lower end vof pipe fand provided with an inlet at the top underneath the supply-pipe of the gasoineter Z) and with a central opening at its -bottoni. A velvet', controlling the said opening, is connected to a float-gage h, so as to close the opening or to open it, accordingly to the level of the water entering the gasorneter. By these niet-ins when supplying water through the inlet-pipe, first, receptacle g is filled up, and then the gasometer b and ves a frame connected to a box which slides on a tube projecting inwardly fronr-the middle of the' bottom of vessel d. A spring inserted into the said tube and bearing with its `lower end .against the bottom of vessel a and with its upper end against the cover of the said box, supports the frame with the receptacle c and presses'it upward, a friction-pawl being provided to hold them in any desired position. Receptacle cis provided with a central opening through which passes the stem of valve z'. Vicks d are supported by the frame connected to the receptacle g, the lower ends of the said Wicks dipping into the water entering gasometer b and their upper ends being in contact with the block of 'carbide of calci um, thus su pplyin g the latter with Water by the capillarity of the wicks. The gas thus generated is assembled in the upper part .of

. gasometer h, from which it escapes through pipe f.

The quantity of generated gas being in proportion to the quantity of water supplied to the block, and the quantity of the latter depending on the depth of immersion of the wicks, it will be understood that in the case of being vgenerated more gas than there will escape through pipe f, the pressure inthe gasolneter will increase, and the level of the water `entering the gasoineter therefore will 4be lowered so as to decrease the supply of water by lessenin g the depth of immersion of the wicks,'and vice versa.

In order to secure a swiftersupply of waterl when the pressure in the gasometer should sink beyond the average inininiuin, I have provided the receptacle g and the float-gage- L, connected to the valve fi, as heretofore described. crease of pressure takes place valve t' is raised and water is directly supplied to the block through the lower opening of receptacle g. An inverted funnel extending from the said opening spreads out the water to a larger extent so as to reach the ends of the wicks which are in contact with the block of car- 'lly these in'eans when the saiddey IOO -bdeof calcium. The supply of Water from receptacle g takes place likewise when the lamp. is to belighted, pipe f with its frame having been previously raised when the lamp has been extinguished, so as to Withdraw the `dipping ends of the wicks from the water in order-to prevent generating of gas. The wicks in this raised position being commonly deprived of water, which drops downward, it would b e somewhat long when lighting the lamp before the .generation of gas begins; but atthe same time, there being only7 the atmospheric pressure in the gasometer, Valve't' is opened `as soon as pipe f is pushed downward to light thelarnp, and there will be generated gas at once by the direct supply ot' water from receptacle g.A

Vh-at l do claim as my invention, and'de- ,sire to secure by Letters Patent, ifs-'- their lower ends into the Walter contained in 3o the vessel a and entering the gasometer b, substantially as set forth and tor the purposes specified. Y

2. In a gas-lamp for burning acetylene gas generated by carbide of calcium subjected to the action of water, consisting of an outer vessel a, a gasometer b provided therein, and provided with an inlet-pipe and outlet-pipe extending through the cover of the vessel, a receptacle containing ablock orplate of carbide 'of calcium placed in the ga'someter b, and Wicks with their Iupper ends in contact with the said block or plate and dipping with their lower ends-into the Water contained in the vessel d and entering the gasometer b, a receptacle g to contain Water, likevvise pla-ced in the gasometer b above the said block or plete and provided with an opening at its bottom, and a float-,gage h connected toa valve 1l fitting in the said opening. 5o

In witness whereof l have hereunto signed my name in the presence of two subscribing Witnesses:
